Toyota Prado 2007 Problems

Prados and Hiluxes have a history of a knocking noise when cold and it was put down to over-fuelling while the engine is warming up. Our understanding is that Toyota fixed the problem by changing the injectors. Ask the dealer to request assistance from Toyota again, although I don’t fancy your chances given that the car has done 120,000 km and you bought it secondhand.

There was a problem with the engines when it they were cold, I understand that it was because of over-fuelling during the time of cold running. I believe Toyota was changing the injectors on complaint vehicles. The leaking injector seals I believe us something else, and the way we know of to check if there is a problem is to inspect the oil pickup in the sump for a build-up of carbon deposits. If the pickup has a carbon buildup the likelihood is that it would eventually block and stave the engine of oil, if there is no carbon present it is unlikely to have a problem. It's best that a dealer check the pickup by inserting a probe through the oil drain hole in the sump.

Take the offer. Like all components fuel-injectors wear out over time and then need replacing. By offering you part payment for repairs Toyota has in effect acknowledged the issue and are offering to compensate you for it. Remember you've had 100,000 km out of the first set.

It doesn't seem normal and you did the correct thing in going back to the installer, but not finding any satisfaction there you should take the car to the system supplier, the Australian LPG Warehouse, and have them assess it for you and hopefully fix it to your satisfaction. The phone number is 1300 574 669.

We have heard a couple of reports of engine seizures because of a blocked oil pick-up caused by a build-up of carbon as a result of leakage past the fuel-injector seals. Toyota issued a service alert in other countries advising that the fuel injector seals be changed every 45,000 km. If the failure of your engine can be attributed to this same issue then I think you have a claim against Toyota. We are aware of one case when the engine was replaced, even though the seized engine had done more than 200,000 km.

Yours is the first report of a problem we have received at Cars Guide. We have passed your report on to Toyota for their response, and in the meantime ask Prado owners to contact us if they have had the same problem.
